LOCKING DEVICE FOR TELEiHONES.

Specification of Letters Patent.

flatcnted July 8, 1913.

Application filed October 11, 1911. Serial No. 654,197.

To (all QUINN/Z it may concern Be it known that I, CHARLES C. Bincrrz, a citizen of the United States, residing at 1571 Atlantic avenue, in the city of Brooklyn and State of New York, have invented certain new and useful Improvements in Locking Devices for Telephones; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention has reference to a convenient and inexpensive means whereby the usual combined telephone transmitter and receiver may be locked so that any one may leave his telephone without fear of its being used by unauthorized persons.

The object of the invention is to supply a simple form of this device which will not have to be removed from the instrument when the same is unlocked and which will nevertheless not be in the way when the instrument is being used.

Certain preferred forms of my invention are shown in the accompanying drawings wherein- Figure l is a perspective view of a portion of a telephone stand, such as is used on stands and desks, the same being shown locked, Fig. 2 is a perspective view of a modified form of a locking device, and Fig. 3 is a similar view of another modification.

The upright stem of the telephone stand is shown at 10 and the usual combined switch and su1')porting lever, which carries the receiver when not in use is shown at 11. As is well known when the lever 11 is in its lowest position as shown in Fig. '1, the switch is closed for signaling but open on the conversation circuit and my improved lock is designed to hold the switch in this position.

At 12 is shown a collar which surrounds the stem of the telephone holder, the same being provided With parallel cars 13 perforated as shown. The collar may be applied to any desired position on the stem by means of a screw let or other appropriate means. A padlock 15 is used for locking the ears I?) and the collar 12 to a yoke which passes over the lever 11. This yoke may take a variety of forms of which I have shown three.

In Fig. '1. the yoke 10 on the lever 11 has two short depending portions 17 between which is secured a link is by means ot a screw 19, the lower end of which link is pertoratcd to receive the hasp of the lock 15. In .llig. 2, the yoke 16 has one long depending side 20 whlch takes the place of the link 18 and atl'ords means tor locking. In Fig. 3, the yoke 1(3 has two long depending sides 21 which lie in contact and are suitably pertorated as shown in Fig. El to be locked to the ears 1 in the manner lmretotore described.

The device is adaptable to various 't'orms ot' stands and has the advantage that when the lock is removed it may be lcl t on the ears [3 and the telephone 'lreely used and it need be a collar '12 may be revolved partly around the stem 10 when the telephone is being used so as to prevent any possibility of the rising and falling ol the yoke 16 being interl'cred with by the rest of the lock.

'hat .I claim is- A telephone lock comprising in combination a flexible remo 'able metal collar having its cxtremitics where they come together turned outward, a Fastening bolt passing through the out-turned portions ot the collar, a, removable yoke arranged to straddle the stem of the switch lever and having an extremity depending into proximity to the out-turned portion of said collar, and a padlock passing through said yoke and said out-turntal portion of the collar, substantially as (.lescribed.

In testimony whereof, I allix my signature, in presence ot two witnesses.
